I. BURNER.

Application filed April 14, 1925. Serial No. 23,129.

This invention relates to burners and more particularly to an improved burner which utilizes hydrocarbon oil of the desired grade, which is thoroughly mixed and commingled with a highly heated gas, said gas commingling in a highly heated state with the hydrocarbon through a heated pipe or pipes before reaching the burner orifices.

A further object is to provide a burner of improved form, the burner per so being located in a plane below the pipe or pipes to be heated, and the flame or flames from said burner functioning to heat the water or air and oil in their passage so as to insure a thorough commingling, a complete breaking up of the oil, and a highly combustible fluid, so that the proportion of oil can be reduced to a minimum and a maximum efli ciency had.

lVith these and other objects in view, the invention consists in certain novel featdrcs of construction and combinations and arrangements of parts which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a plan view illustrating my improved burner;

Figure 2 is a view in side elevation of the burner;

Figure 3 is a fragmentary detail view illustrating a modification.

1 represents a drip pan above which my improved burner is preferably located. The burner element per se is illustrated by the reference numeral 2 and this burner element preferably constitutes four pipes arranged in rectangular form connected by angles 3 and forming a continuous fluid passage, the upper walls of said pipes having burner orifices 4 therein.

While I refer to the burner element per se as of rectangular form and shall describe r in detail the particular construction and arrangement of pipes shown, it is to be distinctly understood that I do not wish to be limited by the language employed, as this language is used to describe the burner in its preferred form as illustrated.

The burner may be supported above the bottom of the pan 2 on suitable feet 5 and a vertical pipe 6 communicates preferably with the central portion of one of the pipes 2. This vertical pipe 6 is connected by an angle 7 with one of a series of parallel pipes 8, 9, 10 and 11, said pipes 8, 9, 10 and 11 being connected by return bends 12, and the p pe 11 having at its inlet end a supply pipe 13, preferably of smaller diameter than the pipe 11 and provided with any suitable valve 14: to control the flowof oil into the pipe 11.

15 represents a supply pipe for water or air. This supply pipe 15 has a valve 16 therein and communicates with a pipe 17 located preferably directly above one of the burner pipes 2. Pipe 17 is connected to a series of parallel pipes 18, 19, 20 and 21 by the return bends 12.

The burner pipes 2, pipe 6 and pipes 18, 19, 20, 21, 8, 9, 10 and 11 are preferably of the same diameter although of course I do not wish to be limited to the particular diameters or their proportions. The pipe 21 is connected by an elbow 22 with a pipe 23, and said last-mentioned pipe 23 is connected by a T-coupling 24 with the pipe 11.

In Figure 3 I illustrate a blower 25 driven by a motor 26 for forcing air under the desired pressure through the pipe 15, and this constitutes a modification of my inventlon, as it is to be understood.- that the pipe 15 may be connected to a water supply un der suitable pressure by gravity or other means while the sup-ply of oil is also under the desired pressure by the employment of any means, not shown.

27 represents a gas supply pipe having a valve 28 therein, and this pipe 27 is connected to a pair of Bunsen burners 29 and 30.

located under the pipes 18, 19 and 10, 11, re spectively.

A post 31 parallel to the pipe 6 serves to support the several pipes 18, 19, 20, 21, 8, 9, 10 and 11 in a tier or plane above the burner pipes 2. For clearness of description I shall distinguish these several pipes as being in the upper or lower tiers.

The operation is as follows:

Assumin that water is employed in combination with the oil, first the valve 28 is opened and the Bunsen burners 29 and lit. The heat from these burners 29 and 30 will heat the upper tier of pipes to the desired temperature. The valves 16 and 14: are then opened. WVater entering the pipe 15 will flow into the pipe 17 and due to the heat of burner 29 will receive almost the same effect as that of a flash boiler so that the elements of the Water Will flow through the pipes 18, 19, 20, 21 and 28 into the pipe 11, joining and commingling With the oil and serving to separate or break up the oil into finely divided particles thor oughly associated With the Water elements to form a highly combustible gas, and this gas will flow through the pipes 11, 10, 9 and 8 and pipe 6 to the burner pipes 2, it being understood of course that the temperature of the gas Will not only be maintained but Will be increased during such passage.

As this combustible gas reaches the burner pipes 52 it is ignited at the orifices E and will burn from said orifices, and the temperature of the flames will heat the upper tier of pipes so that the Bunsen burners 29 and 30 can be shut off.

If air is used, a blower or other means such as indicated in Figure 3 may be cmployed to blow air through the pipe 15 into the pipe 17, and as this air expands and is heated it Will oommingle with the oil and the mixture Will burn through the orifices 4, as above explained.

It Will thus be noted that the Water or the air, as the case may be, is separately heated before it oommingles with the oil, and, after commingling, the mixture is increasingly heated so that a perfect gas is had, resulting in an economy of fuel and a maximum of heat units of efiiciency.

While I have used the term pipe to describe various parts of the burner, it is to be distinctly understood that the burner may constitute ordinary pipes With cou plings, as explained, or passages from itotherwise formed, and I do not Wish to be limited by the employment of this term p p F or convenience in the claims I shall refer to the pipe 17 and its coi' necting elements as a Water pipe, but as above explained it may be used for air, and I do not Wish to be limited in the claims to the use of Water as it is my purpose to claim the burner construction as a construction adapted for use in connection with Water, air or other gas in combination with oil.

Various slight changes and alterations might be made in the general form of the parts described Without departing from my invention, hence I do not Wish to limit myself to the precise details set forth but consider myself at liberty to makesuch slight changes and alterations as fairly fall Within the spirit and scope of the appended claims.

I claim: Y

1. A burner of the character described, comprising a rectangular burner, comprising pipes and elbows, the pipes having perforations therein, an oil pipe located in a plane above the burner and having a series of con-- nected runs extending from the outer plane of the burner to an intermediate. plane of the burner, a vertical pipe connecting the end of the oil pipe directly With the burner and functioning as a support for said oil pipe. a fluid pipe located in substantially the same plane as the oil pipe and comprising a series of connected runs extending from the outer plane of the burner to a point intermediate the ends thereof, and a pipe connecting said fluid pipe With the 'oil pipe.

2.
